Starts a disaster recovery drill to ensure the continued replication and clone the data from the last recovery point of the secondary disk to a new disk. This helps you test the completeness and correctness of applications that are deployed on the disaster recovery site on a regular basis.
Operation description
After the disaster recovery drill is complete on the secondary disk, a pay-as-you-go drill disk that has the same capacity and category as the secondary disk is created in the zone where the secondary disk resides. The drill disk contains last-recovery-point data that can be used to test the completeness and correctness of applications.

Request parameters
| Parameter | Type | Required | Description | Example |
|---|---|---|---|---|
| RegionId | string | Yes | The region ID of the secondary disk in the replication pair. You can call the DescribeDiskReplicaPairs operation to query the region in which the secondary disk of the replication pair resides. Note
You must enable the disaster recovery drill feature in the region in which the secondary site resides.
| cn-hangzhou |
| PairId | string | Yes | The ID of the replication pair. You can call the DescribeDiskReplicaPairs operation to query a list of replication pairs, including replication pair IDs. | pair-xxxx |
| ClientToken | string | No | The client token that is used to ensure the idempotence of the request. You can use the client to generate the token, but you must make sure that the token is unique among different requests. The token can contain only ASCII characters and cannot exceed 64 characters in length. For more information, see How to ensure idempotence. | 123e4567-e89b-12d3-a456-42665544**** |
